Specification of Letters Patent.

Patented Feb. 2, 1909.

Application filed April 27, 1908. Serial No. 429,485.

To all whom it may concern:

Be it known that I, JOSEPH RYAN, a citizen oi the United States,residing at Somerville, in the county of Morgan and State of Alabama,have invented a newand useful Detachable Ax, of which the following is aspecification.

This invention relatesto that class ofaxes,

which are provided with detachable cutting blades or bits, which can berenewed, when destroyed or worn out.

The object of this invention is to provide an improved ax of this kindin which the bit or blade can be readily detached and 're-.

newed, and in which'the bit or blade is firmly and securely held inplace.

The invention consists of an improved ax having a detachable bit orblade" and in details thereof, constructedand arranged, as hereinafterset forth and claimed.

Referring to the accompanying drawing;

Figure 1 is a side view in vertical section of an ax constructed inaccordance with this invention. Fig. 2 is an elevation'incross sectionon the line X-X Fig. 1. Fig. 3 is a perspective view of the ax head withbit removed. Fig. 4 is a perspective view of the bit detached and Figs.5 and 6 are perspective views showing the wedges.

In the construction of this invention the body 1, 01" an ax is providedwith a detach l':le bit or blade 2. The body 1 is formed with the socket3, in which is inserted the handle 4, the lower edge 5 of the handleprojecting into and extending along a V shaped recess 6, in the body 1,adjacent to and opening into the socket 3. The body 1, is further formedwith a central passageway 7, extending from its lower end andcommunicating with the recess 6 transverse thereto. The bit or blade 2is formed with a central projection or member 8, which extends throughthe passageway 7, and projects into the recess 6. To seat the bit 2steadily in place on the body 1, the latter is formed with thelongitudinal projections or tongues 9, on either side of the opening ofthe passageway 7, and the shoulders 10, on the sides of the projections9. The bit 2is formed with the ongitudinal recesses 11, on either sideof the of the recesses 11. When the bit 2 is in position on the body 1,the. projections 9, are located in the recesses 11, and the flanges 12rest against the shoulders 10, thus forming a snug joint. To furthersteady the bit, it is provided with pins 13, which engage holes 14 inthe body 1.

To firmly and securely hold the bit 2 to the body 1 a trough shapedstrip 15is inserted lengthwise in the upper'part of the V shaped recess6, the strip 15 being formed with a longitudinal recess 16 havingtapering sides in which rests the lower edge 5, of the handle 4. Thestrip 15 is also formed with the central opening 17, which is inalineinent with, and is located at'the upper end of the passageway 7.The projection 8 is formed at its end with the transverse hole 18, andextends through the opening 17 into the recesses 16. A tapering wedge19, which also tapers from its end 20 to its end 21, is insertedlengthwise through the bottom of the V? shaped recess 6, and through thehole 18, and locks the bit 2 to the body 1. The wedge 19 is held, inlace preferably by a set screw 22 in the end of wedge 19, the head ofthe set screw 22 bearing against the body of the The strip 15-is firmlywedged in the recess 6, with the lower edge 5 of the ax handle wedged inthe recess 16, and the wedge 19 is in turn wedged against the bottom ofstrip 15.

By means of the construction hereinbefore set forth, the bit is firmlyseated against the head of the ax, and is securely locked thereto. Thewedging parts in the recess adjacent to the. handle socket of the ax,serve, in addition to securing the bit to the body of the ax, to firmlyand securely hold. the ax handle in its socket.

Having described the invention, 1 claim:

1. The combination in an ax, of an ax head or body having a handlesocket, a handle fitting therein, a removable bit, and a locking meansfor holding the bit to the head and servingalso to wedge the handle inits socket.

2. Anax formed with a body and detachable bit, the body having atransverse passageway o ening into the handle socket, and a longitu inalpassageway opening into the transverse passageway; the bit having aprojection extending through said longitudinal passageway, and into thetransverse assageway an ax handle, and means for ocking said projectionat its end in said transverse passageway which also wedges tachable bit,the body having a transverse recess adjacent to the handle socket, and alongitudinal passageway opening into said transverse recess; an axhandle, and a bit I having a projection extending through saidlongitudinal passageway, and into the transverse recess with a recessedend located in said recess, and means for locking said end in saidrecess which also wedges said handle in its socket.

4. An ax having a detachable bit, the body of the ax head being formedwith a V shaped recess opening into and in alinement with the handlesocket, and a longitudinal passageway opening into said V shaped recess,a bit having a projection extending through said longitudinal passagewayand into the "\i' shaped passageway, an ax handle, and means for lockingthe bit projection, the body and handle together.

5. An ax with a detachable bit, the ax head having a recess opening intoand in alinelncnt with its handle socket, and a longitudinal passagewayopening into said recess, a bit having a projection in said passagewayand extending into said recess, an ax handle projecting laterally intosaid recess and means for wedging and locking the handle, the head andbit together.

6. An ax with a detachable bit, the ax having a recess 0 ening into, andin alineinent with its handle socket and a longitudinal passagewayopening into said recess, a bit having a projection in said passagewayand extending into said recess, an ax handle projecting laterally intosaid recess, and wedges, wedging said handle, and lock ing said bitprojection.

7. An ax with a detachable bit, the ax having a V shaped recess openinginto, and in alinenient with the handle socket, and a longitudinalpassageway opening into said recess, a trough shaped wedge with taperingsides and central opening, located in said recess, a bit having aprojection extending through the longitudinal passageway and into thetrough shaped wedge, an ax handle wedge in said wedge, and engaging thebit projection.

8. An ax with a detachable bit, the ax having a V shaped recess openinginto and in alinelnent with the handle socket, and a longitudinalpassageway, opening into said recess, a trough shaped wedge withtapering sides and central opening, located in said recess, a bit havinga projection, with a perforated end, extending through said 1longitudinal passageway, and into the tron gh shaped wedge, a wedgelocated in the V shaped recess and extending through the perforated end,and an ax handle wedge engaging said trough shaped wedge and saidperforation.

9. An ax with a passageway opening into and in alineinent with itshandle socket, and a longitudinal passageway, opening into saidpassageway, slotted and recessed wedge located in the first nainedpassageway, an ax handle seated in said recessed wedge, a detachablebit, with a projection having a. transverse perforation at its end,extending into the slotted recessed wedge, a wedge extending throrgh thefirst named passageway, and through the perforated end, and means forlocking said wedge to the ax head.

10. An ax having a recess extending lengtlrwise of, and opening into thehandle socket, and passageway transversely to and opening into saidrecess, an ax handle, a wedge in said recess engaging the ex handle, adetachable hit having a projection with a transverse perforation at itsend, engaging said wedge, a tapering wedge ex tending throngh saidperforation and wedging the projection to the first named wedge, and alocking device 011 the end of the tapering wedge.

11. An ax consisting of a body formed with a J shaped nrssageway,opening into the handle socket, a longitudinal passageway opening intothe V shaped passageway; and shouldered projections or tongues withholes on its lower end, a detach: ble bit having a projection with anopening throngh its end, and flange walled recesses with pins adjacentto said projection in which the said shouldered projections are seated;the bit projection extending through the body and into the V shapedpassageway: a tr gh shaped wedge with central opening, located. in saicV shaped passageway, an ax handle resting in said wedge; and a taperingwedge located in said V shaped passageway, and extending through theopening in the end of the bit projection.

In testin'rony that I claim the foregoing as my own, I have heretoallixed my signature in the presence of two witnesses.
